Frequently Asked Questions
What is a cap table?
A capitalization table (cap table) tracks who owns what percentage of a company. It includes founders, investors, option pools, and any convertible instruments. It changes with each funding round.
How does dilution work in a funding round?
When new shares are issued to investors, existing shareholders' ownership percentages decrease (dilute). If you own 50% of 1M shares and a round issues 500K new shares, you now own 33% of 1.5M shares — even though your share count didn't change.
What is a liquidation preference?
A liquidation preference guarantees investors get their money back (usually 1x their investment) before other shareholders in an exit. With a 1x non-participating preference, investors choose between their preference amount or their pro-rata share of proceeds — whichever is higher.
